JOSEPH D. DAVENPORT, OF PAWTUGKET, RHODE ISLAND.

ADJUSTABLE STAGING-BRACKET.

EiPECIFIOATION forming part of Letters Patent No. 319,4;63, dated June 9, 1885.

Application filed May 2, 1885.

I0 aZZ whom, it may concern.-

Be it known that I, J osnrn D. DAVENPORT, of Pawtucket, in the county of Providence and State of Rhode Island, have invented an Improvement in Adjustable Staging-Brackets, of which the following is a specification.

In constructing and repairing buildings it is highly desirable to provide a readily-arranged and convenient staging that can be rapidly removed from one place to another, as required 5 and to this end it is the object of my invention to provide an improved adjustable staging-bracket which may be readily secured in proper position for general use, being of simple and inexpensive construction, and which may be packed away in small compass for transportation; and my invention consists in the improved combination of parallel bars with joint and clamping bolts and. holdingspurs, wherebya readily attachable and detachable holding-bracket is produced adapted for general use, as hereinafter set forth.

Figure 1 represents the front elevation of a house, and shows the application thereto of my improved stagingbracket. Fig. 2 is a perspective view of my improved adjustable staging-bracket with the end of one of the bars broken away in order to show the fasteningspurs attached to the inner face of the opposite parallel bar. Fig. 3 represents a plan and central section of the spurplate to be inserted into the inner face of the ends of the parallel bars. Fig. 4 represents the transverse section of a partially-finished house, and shows the application of my improved staging-bracket thereto. Fig. 5 represents a sectional view of my improved stagingbracket combined with an upright bar and fastening-bolt to form a carpenters jack.

In the accompanyipg drawings, Fig. 2, A A are two parallel bars, which may be made about four feet in length, one and one-eighth of an inch in thickness, and three and onehalf inches in width. The said bars are each provided at one end with a series of holes, a a a, adapted to receive a bolt, I), which serves to form a joint with the similarly-perforated bars B l3.

The outer ends of the bars A A and B B are provided with a hole, 0, adapted to receive the clamping-bolt d, and each of said bars are provided at their inner sides,bey0nd the bolt (No model.)

d, with a plate, 6, having projecting-spurs f, which are preferably made integral with the plate, and the plate 6 may be secured to the inner side of the bars by means of the screw 9 and a recess made in the bar of sufficient depth to embrace the periphery of the plate 6.

In order that the space h between the bars A A and BB shall be of sufficient width to properly embrace the sides of an ordinary scantling, I apply a sleeve or washer, t, to the bolt 1), thus increasing the distance between the parallel bars, and by means of the holes a a a in the bars A A and B B the connecting-j oint may be changed relatively to the ends of the bars, as desired.

Having thus described my improved stag ing-bracket, I will now explain the manner of using the same, first, in the construction of a masons scaffold for finishing off a chimney, as shown in Fig. 1, and in this case two pieces of scantling, O O, are jointed together at one end and arranged over the peak of the roof at one side of the chimney, one of the scantlings O extending downward upon one side of the peak, and the other scantling 0 extending upon the opposite side of the same, while a similar pair of j ointed scantlings is placed over the peak at the opposite side of the chimney. The brackets are then applied to the scantling by screwing the spurred ends of the bars against the opposite sides of the scantling, and when four of the brackets have been thus clamped to the scantling a flooring, D, is to be laid over the two opposite brackets, upon which flooring the mason may stand while performing his work, and upon which he may safely deposit his building material.

The brackets may be quickly adjusted in any desirable position upon the scantling O,

and are firmly held thereon by means of the bolts 01, which are provided with a thumb-nut.

WVhenever the brackets are removed from the scantling, the jointed bars A and B may be folded alongside of each other, so as to occupy but little space, and may thus be readily transported from place to place. 1

In arranging my improved clamping-brackets to form a carpenters staging for work at the side of a house, twoor more scantlings, E, may be provided and set in an inclined position, as. shown in Fig. 1, and at the proper point upon the same I clamp the bracket by means of the bolts cl, thus forcing the spurs f into the opposite sides of the scantling and securing a firm hold thereon. Boards or plank D of sufficient thickness are then to be made to extend from one bracket to the other, and upon the staging so constructed the carpenter can perform his work in perfect safety.

In Fig. at my improved staging-bracket is represented as secured to the studding 7c of a partly-finished building, the bracket being clamped to the studding by means of the bolts (1 and spurs, as hereinbefore described.

My improved bracket is also adapted for the ready construction of a carpenters jack, as shown in the sectional View, Fig. 5, which shows the bars A and B for one side of the bracket, and also a bar, F, which is to be clamped firmly between the parallel bars A A and B B. The lower end of the bar F is provided with a notch, m, adapted to receive the body of the bolt d, and the bolt d is prevented from escaping from the notch m by means of the hook n, which is driven into the edge of the bar 1 immediately below the notch m.

The upper end of the bar F is perforated to receive the hook-bolt 0, upon which is placed anut, p, and by means of the nut 19 and hookhead q of the bolt 0 the body of the clamping: bolt 61 is firmly held against the edge of the bar F. In securing the jack so formed to the side of a building, as shown in Fig. 4, a hole is first bored through the sheathing or studding and the bolt 0 of the jack inserted therein and firmly screwed up by means of the nut r, thus forming a very strong and efficient device, which may at the same time be readily taken apart and reduced to a small compass.

I claim as my invention- In a staging-bracket, the combination of the parallel bars A A and parallel bars B B, o

jointed to the bars A A by means of the bolt 1), clamping-bolts d d, and holding-spurs f,- substantially as described.
